<h4><a name = "tag_000_005_806">&nbsp;</a>NAME</h4><blockquote>
getwc - get a wide character from a stream
</blockquote><h4><a name = "tag_000_005_807">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="stdio.h.html">stdio.h</a>&gt;
#include &lt;<a href="wchar.h.html">wchar.h</a>&gt;

wint_t getwc(FILE *<i>stream</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_005_808">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>getwc()</i>
function is equivalent to
<i><a href="fgetwc.html">fgetwc()</a></i>,
except that if it is implemented as a macro it may evaluate
<i>stream</i>
more than once, so the argument should never be an expression with side
effects.
</blockquote><h4><a name = "tag_000_005_809">&nbsp;</a>RETURN VALUE</h4><blockquote>
Refer to
<i><a href="fgetwc.html">fgetwc()</a></i>.
</blockquote><h4><a name = "tag_000_005_810">&nbsp;</a>ERRORS</h4><blockquote>
Refer to
<i><a href="fgetwc.html">fgetwc()</a></i>.
</blockquote><h4><a name = "tag_000_005_811">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_005_812">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
Because it may be implemented as a macro,
<i>getwc()</i>
may treat incorrectly a
<i>stream</i>
argument with side effects.  In particular,
<i>getwc</i>(*<i>f</i>++)
will not necessarily work as expected.  Therefore, use of this interface is 
not recommended;
<i><a href="fgetwc.html">fgetwc()</a></i>
should be used instead.
</blockquote><h4><a name = "tag_000_005_813">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_005_814">&nbsp;</a>SEE ALSO</h4><blockquote>
<i><a href="fgetwc.html">fgetwc()</a></i>,
<i><a href="stdio.h.html">&lt;stdio.h&gt;</a></i>,
<i><a href="wchar.h.html">&lt;wchar.h&gt;</a></i>.
</blockquote><h4>DERIVATION</h4><blockquote>
Derived from the MSE working draft.
